Glossy Vitamin Bottle Inspection Example

In this example, we are inspecting a printed lot code on the bottom of a bottle. Due to the

reflective and concave characteristics of the bottom of the bottle, it is difficult to illuminate the

printed lot code without excessive specular reflections.

Figure 9 - Input images of the glossy vitamin bottle.

However, by using a DF198 MicroBrite

Diffuse

Ring Light with each of its four quadrants

independently controlled with the DCS-400E Quad

Controller, we are able to capture four images with

illumination at the same angle of incidence, but

from multiple directions.

Using the Matrox Design Assistant and Imaging

Library (MIL) to process the images, the final

albedo of the image is flat – resulting in an easily

identifiable printed lot code.
